查询词典 circle

The relationship between the minimum zone circle, minimum circumscribed circle and maximum inscribed circle was studied. Based on their relationship, the minimum zone circle and minimum circumscribed circle, maximum inscribed circle were transformed mutually.

本文研究了最小区域圆与最小外接圆、最大内接圆特征点的相互关系，实现了最小区域圆与最小外接圆、最大内接圆的相互转化，可有效解决最小区域圆的误差评定。

Thus, evaluation of the minimum zone circle could be solved effectively.Three methods of assessment of roundness error were proposed in this dissertation. Based on the criteria of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle and convex hull, a unified approach was proposed to evaluate roundness error of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle. Evaluation of the minimum zone circle, minimum circumscribed circle and maximum inscribed circle was fulfilled with rotation based the contact pattern. The minimum circumscribed circle and maximum inscribed circle were evaluated with curvature and the curvature circle.

本文提出了三种圆度误差评定的方法：根据最小区域圆、最小外接圆、最大内接圆在极坐标系下的判别准则，利用计算几何中的凸壳理论，提出了一种统一的评定方法，实现了对最小区域圆、最小外接圆、最大内接圆的误差评定；基于接触斑点的检验原理，利用旋转法，实现了最小区域圆、最小外接圆和最大内接圆的误差评定；利用曲率和曲率圆，实现了对最小外接圆和最大内接圆的误差评定。

Yangtze Delta Urban Economic Circle, Zhujiang Delta Urban Economic Circle, Beijing-Tianjin-Hebei Urban Economic Circle, Chengdu-Chongqing Urban Economic Circle, and Wuhan Urban Economic Circle are five important urban economic circles, among which, four economic circles except Wuhan Urban Economic Circle have club convergence phenomenon and this club convergence is greatly related to industrialization degree, inner economic structure and innovative ability of the five economic circles.

长江三角洲城市圈、珠江三角洲城市圈、京津冀城市圈、成渝城市圈、武汉城市圈是我国五个重要的城市圈；其中，除武汉城市圈外其他四个城市圈均存在不同程度的俱乐部趋同，而且这种趋同和五大城市圈的工业化程度、内部经济结构及创新能力有很大关系。

First, this article introduced 2 grade of rotary kiln principle of work and the equipment, to rolled the circle mechanics behavior to carry on the analysis, proposed - rolled the circle - under roller's rotary kiln overall modelling based on the tube body - kiln liner - big tooth ring, to rolled the circle - under roller's contact stress to carry on the finite element analysis the method, and obtained rolled the circle contact stress the size and the distribution rule, finally indicated that rolled the circle contact stress mainly to have two main peak values and the sudden change in one week, appeared is rolling the circle and the under roller contact area; Then, rolls the circle the stress to regard as is the principal stress unknown plane stress test, the use quite mature modern test technology, proposed rolls the circle stress test the principle and the plan, and to rolled the circle the stress to carry on the scene test, the stress which the scene test analysis result and the finite element analysis calculated has compared, had proven the whole method modelling's finite element analysis method's rationality and rolled the circle - under roller contact stress the result accuracy; Finally, uses ANSYS APDL the re-development technology, in view of 2 grades of rotary kilns, rolled the circle - under roller contact stress the overall finite element analytic method to carry on the re-development.

首先，本文介绍了2档回转窑工作原理和装置，对滚圈的力学行为进行了分析，提出了基于筒体-窑衬-大齿圈-滚圈-托轮的回转窑整体建模，对滚圈-托轮的接触应力进行有限元分析的方法，并得到了滚圈接触应力的大小和分布规律，结果表明滚圈接触应力在一周内主要存在两个主要的峰值和突变，都出现在滚圈与托轮接触区域；然后，把滚圈的受力看成是主应力未知的平面应力的测试，利用比较成熟的现代测试技术，提出了滚圈应力测试的原理和方案，并对滚圈的应力进行了现场测试，现场测试分析结果与有限元分析计算出的应力相比较，证明了整体法建模的有限元分析方法的合理性和滚圈-托轮接触应力的结果的正确性；最后，利用ANSYS的APDL的二次开发技术，针对2档回转窑，就滚圈-托轮接触应力的整体有限元分析法进行了二次开发。

The quorum cluster including only three quorums is a small quorum system; every two quorum clusters intersected only one quorum. Circle quorum system used self-adaptive fault-tolerant protocol, which decided to use voting protocol or mutual exclusion protocol based on the failure probability and number of points of one quorum.

Circle Quorum系统采用了自适应容错协议，根据quorum内部节点的非等失效概率和失效个数决定采用选举协议还是互斥协议。quorum中所有节点组成选举quorum，其中，具有高可靠性的若干节点组成高性能响应子quorum。
